7 Winter Energy Saving Tips for Businesses
Winter brings colder weather, precipitation, and holidays, all of which can drive up energy demand. While summer peaks often get more attention, winter also sees high energy use, primarily because heating a space typically requires more energy than cooling it. By understanding what causes winter energy peaks and implementing strategic changes, businesses can significantly reduce their utility bills and overall energy consumption.
Understanding the Winter Energy Peak
An energy peak is the period of highest electricity demand. The winter peak typically occurs in the morning from 6:00 to 9:00 a.m., as businesses open and days begin, and again in the evening from 4:00 to 8:00 p.m., when people return home and ramp up heating and appliance use.
Key Factors Driving Winter Energy Demand
Heating Systems: As temperatures drop, heating systems work harder to maintain comfortable indoor temperatures. Buildings that rely on electric heating systems will see a direct and substantial increase in their electricity consumption.
Shorter Days: With fewer daylight hours, the reliance on artificial lighting increases significantly, contributing to higher electricity usage throughout the workday.
Geographic Location: Regions with harsher winters will naturally have higher energy demands for heating and hot water.
Holiday Season: Increased decorative lighting, cooking, and gatherings during holidays like Christmas and New Year's further elevate energy consumption.
Winter vs. Summer Peaks at a Glance
Peak Hours:
Winter: 6:00-9:00 a.m. & 4:00-8:00 p.m.
Summer: 4:00-9:00 p.m.
Primary Energy Uses:
Winter: Space heating, water heating, and lighting.
Summer: Air conditioning and refrigeration.
7 Practical Tips to Reduce Winter Energy Bills
Conduct a Pre-Winter Energy Audit and Maintenance
Schedule a professional energy audit to identify inefficiencies in your building's envelope and equipment. Combine this with a thorough HVAC system maintenance check. Cleaning components, checking for issues, and ensuring optimal performance can improve efficiency, prevent winter breakdowns, and extend the system's lifespan.
Replace Air Filters Regularly
Clogged air filters restrict airflow, forcing your heating system to work harder and consume more energy. Check filters frequently during high-usage periods and replace them as needed-at a minimum, every three months. For furnace systems, pay attention to the filter's MERV rating to ensure both efficiency and proper airflow.
Optimize Thermostat Settings
For every degree you raise the thermostat, energy use increases by 3-5%. Set your thermostat to 68°F (20°C) during business hours. During unoccupied hours, nights, and weekends, lower the setting significantly to 56-60°F (13-15°C). A programmable or smart thermostat can automate these adjustments for maximum savings.
Inspect Ductwork and Vents
Blocked, leaky, or dirty ducts can waste a substantial amount of heated air. Before winter, inspect ductwork for leaks and ensure all vents are clear of obstructions like furniture, boxes, or rugs. Proper sealing and clear pathways allow for efficient airflow and distribution of heat.
Upgrade to LED Lighting
Winter's shorter days mean lights are on for longer. Replacing traditional incandescent, halogen, or fluorescent bulbs with LEDs can reduce lighting energy consumption by up to 90%. LEDs also have a much longer lifespan, lowering both your energy bills and maintenance costs.
Install Window Films
Windows are a major source of heat loss. Applying insulating window film creates a thermal barrier that reduces heat escape in the winter. This simple upgrade helps maintain a consistent temperature, reduces strain on your heating system, and can also block solar heat gain in the summer.
Leverage Flexible Work Policies
On days when it's feasible, encourage work-from-home policies. With fewer people in the office, you can reduce the need for heating, lighting, and appliance use in less occupied spaces, leading to direct energy savings while supporting employee flexibility.
The Bigger Picture: Benefits of Energy Efficiency
Reducing your winter energy peak isn't just about cost savings. It also lowers your business's carbon footprint by reducing the demand for fossil-fuel-powered electricity. Furthermore, energy-efficient properties often have a higher market value and are more attractive to potential buyers or tenants, offering an excellent return on investment.
By implementing these strategies, businesses can create a more sustainable, cost-effective, and comfortable environment throughout the winter season.
